Well nice psychological question as you may call it but getting to ignore people who do not share interest in same thing with you actually depends on how you handle there issues.
Well I'm not someone that follows what people say or pay attention to unnecessary topic rather I prefer generating my our findings,
So by doing that I won't be influenced to do what they do so I make my own choice and live them with no option but to go by my will.
you can decided to ignore what people are saying if you choose not to give respond OR work with their advice .
sometime is good to be yourself just to remain focus and it this will definitely bring more confident to you and also believing in yourself
